Perform segue after Login successful in Storyboards

由 偶尔善良 提交于 2019-11-26 18:29:59
问题 I have 2 UITextFields , one of them for Login and the another for the Password. Only if the Login is "succesful", I want to perform the Segue with Push to another View Controller . But when I touch the button, directly the View push to the Another View without check the Condition. In StoryBoard I drag from the UIButton to the View Controller I want to push, for creating the segue with push option. Here is my code: - (IBAction)buttonLogin:(id)sender { if (([self.textFieldLogin.text

Embed a UIViewController in a NavigationController using segues

问题 I have a viewController that is usually (most often) accessed by using a push segue. This viewController needs to be embedded in a UINavigationController. So typically, this is no problem. The push segue manages pushing the viewController, and therefore the viewController has it's UINavigationController. My issue is that in a few cases, I'd like to present this same exact viewController using a modal segue. When I do this, the viewController is not embedded in a navigationController. Is there

I'm facing the error message: "UIStoryboardSegue does not have a member named 'identifier'" Here's the code causing the error if (segue.identifier == "Load View") { // pass data to next view } On Obj-C it's fine using like this: if ([segue.identifier isEqualToString:@"Load View"]) { // pass data to next view } What am I doing wrong? This seems to be due to a problem in the UITableViewController subclass template. It comes with a version of the prepareForSegue method that would require you to unwrap the segue. Replace your current prepareForSegue function with: override func prepareForSegue

Pass data between ViewController and ContainerViewController

问题 I'm working on an app, and need to pass data between view and containerView. I need to send data and receive data from both Views. Let me explain better: I can change the Label Master (Touch the Container Button) by protocol , but I can not change the Label Container (Touch the Master button). What happens is the Master connects with the container by a following. But do not have a follow Container linking to the Master. I tried to add but segue to, but it worked. The Master View Controller:

Does anyone know what the new Exit icon is used for when editing storyboards using Xcode 4.5?

问题 Right-clicking the Exit icon yields an empty window. Can't Ctrl-drag a connection to any IB elements or corresponding source files. Docs give no love. Doesn't appear in nib files, only storyboards. My assumption is that it's a corollary to segues, but I don't see any new methods to back it up. Anyone? 回答1: There's a lot of information in the WWDC video "Session 407 - Adopting Storyboards in your App." Say you have two view controllers linked by a segue. Implement the following exit action on

问题 I have been working on this app for months now and from as far back as I can remember I have never had an issue with segues. The code is unchanged in terms of calling performSegueWithIdentifier but since my recent update to Xcode 7 and iOS 9 I have not been able to tack this issue. I have tried: Deleting button and creating new button w/ segue link Using a direct segue from button to view, without the use of performSegueWithIdentifier Connecting button to new blank viewController When I press

问题 I have been trying everything for hours, and nothing\'s worked. I am trying to segue between two view controllers, from one tableViewController to another tableViewController.

It was working fine last night, but now i can\'t seem to get it to segue without crashing. here are the methods in which the segue is called - (void

Here is the method in which I have the line showSegueWithIdentifier : - (void)tableView:

How do I create a segue that can be called from a button that is created programmatically?

由 风格不统一 提交于 2019-11-26 06:38:08
问题 In Swift I have a button created programmaticaly using: var button = UIBarButtonItem(title: \"Tableau\", style: .Plain, target: self, action: \"tabBarTableauClicked\") I want that when the user clicks the button it changes viewControllers. Here is the code for tabBarTableauClicked : func tabBarTableauClicked(){ performSegueWithIdentifier(\"tableau\", sender: self) } But it is obviously not working because there is no segue with an identifier called \"tableau\". And I can\'t create a segue
